No, no, my idea was a setup like the following:
TP<-->Car adapter (from IBM or Xtend or Lind or whoever)<-->battery pack.
The adapter already does the conversion between the TP DC input and the car battery 12vdc output. If I already had one of these converters, I might spend the money for the battery pack just to see how well it works; however, I really don't want to spend $50-$100 for the adapter (which I will never use otherwise) on top of the battery cost. (BTW, if anyone wants more info, I get catalogues from several photo companies who sell such packs, I can quote some representative prices and specs.)
